What Standard Library Packages Can Be Imported in the Go Playground?
Packages Importable in the Go Playground
Q: What packages can be imported when using the Go playground (http://play.golang.org/)?
A: The Go playground allows imports from most packages within the standard library, as stated in the “About” button on the playground.
Exceptions to Importability
The standard library packages that cannot be imported in the playground are:
- Packages not found in the "Packages" page under the "Standard library" section.
- Runtime packages with missing Go type information (e.g., runtime/cgo).
Playground Implementation
For a detailed explanation of the playground implementation, refer to "Inside the Go Playground" published on the Go Blog.
Exhaustive Playground Test
The following code demonstrates the importability of all standard library packages (excluding non-buildable packages):
package main import ( // ... imports for all standard library packages listed in the "Packages" page ... ) func main() { println("ok") }
This code imports all standard library packages except runtime/cgo, which gives a compilation error due to missing Go type information.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.

Golang is better than C in concurrency, while C is better than Golang in raw speed. 1) Golang achieves efficient concurrency through goroutine and channel, which is suitable for handling a large number of concurrent tasks. 2)C Through compiler optimization and standard library, it provides high performance close to hardware, suitable for applications that require extreme optimization.

Golang and Python each have their own advantages: Golang is suitable for high performance and concurrent programming, while Python is suitable for data science and web development. Golang is known for its concurrency model and efficient performance, while Python is known for its concise syntax and rich library ecosystem.

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.

Golang is suitable for rapid development and concurrent scenarios, and C is suitable for scenarios where extreme performance and low-level control are required. 1) Golang improves performance through garbage collection and concurrency mechanisms, and is suitable for high-concurrency Web service development. 2) C achieves the ultimate performance through manual memory management and compiler optimization, and is suitable for embedded system development.

Golang and C each have their own advantages in performance competitions: 1) Golang is suitable for high concurrency and rapid development, and 2) C provides higher performance and fine-grained control. The selection should be based on project requirements and team technology stack.
